ABAC for MCP gives infrastructure teams a way to control model-initiated actions with real runtime context instead of broad static permissions.
The core policy model
- Subject attributes: who is acting, current authority level, and ownership context.
- Resource attributes: what is targeted, sensitivity tier, and potential blast radius.
- Action/context attributes: operation type, environment conditions, and change-window state.
Execution safety pattern
Start with read-only defaults, gate high-risk write actions behind named approvals, and log recommendation-to-execution lineage for audit evidence.
This approach helps teams preserve operational speed while making authorization decisions defensible to security and compliance leadership.
